Field Activity 1983-007-FA

Identifier 1983-007-FA
Alternate names 83-2
Purpose Identify heavy mineral deposits and shallow gas on the insular shelf of northeastern Dominican Republic.
Location Bahia de Samana (Samana Bay), Dominican Republic, North America, North Atlantic;
Summary Seismic data indicated the presence of shallow gas near the western end of Bahia de Samana. Dominican geologists later told us gas had been discovered onshore near the area surveyed. Mud diapirs are a common feature in the sediments underlying the western port of Samana Bay. The bay is bounded in the north and south by faults extending parallel to the coasts.
